Title: Insulating gate type field effect transistor and its preparation
Inventor: TANIGAWA YOSHIKI
IPC: H01L29/10
Filed: 1978-12-14
Abstract: PURPOSE:To accurately control the width of a channel region, and to improve yield, by separating a portion between a source and a drain of a double diffusion type IG-FET by means of a groove, and by mounting a gate electrode into the groove through an insulating layer. CONSTITUTION:A p-type channel dope region 2 is formed by selectively diffusing p-type impurities to a p-type semiconductor substrate 1 with low concentration from a window 5 of an oxide film mask 6. An n<+>-type region 7, which is shallower than the p-type region 2 and which one portion stacks to the region 2, is selectively made up by using the other oxide film mask. The n<+>-type region 7 is divided into two independent regions 3, 4 by etching the substrate in an aeolotropic shape from a window 8 of the oxide film 6' again built up, and a concave portion 9 is formed so that the channel dope region 2 be exposed. A gate electrode G is mounted to the concave portion 9 through a gate insulating film 10, and a source electrode S and a drain electrode D are installed to the n<+>-type regions 3, 4. Thus, the width of the channel can precisely be controlled.
